TWRP Recovery Failed - OnePlus 2 Q&A, Help & Troubleshooting

Hey all, I'm new to android and new here. I succeeded in rooting my phone and added Twrp recovery. But whenever I try and do a backup in Twrp it fails saying: E:Unable to mount '/cache'
Not sure if it is acceptable, but if I don't select cache in the backup, it succeeds. I guess my worry is that this is a deeper underlying issue that will cause me problems later.
I thought about flashing everything back to stock and redoing it, but don't want to cause any more problems before I got some advice.
Any help or insight would be appreciated. Thanks.
Twrp version: OnePlus2 TTF TWRP by ydss.cn v2.8.7.0

Flashing cache may not work at all, given cache storage is so small. You can flash it without checking for cache, it doesn't make too much of a difference except that you won't get your cache. For general use, its not too big of a deal to have cache or not, as it will be recreated as you run your OS later on.

[Q] Error Mounting Cache

Hey guys.
Got a GT-I9505 and was trying to look at some custom ROMs to install, even thinking of giving the beta AOKP a go, but I ran into an issue.
I was first able to gain root access without much issue from the pre-installed firmware, worked through Odin like a treat, but after I went to install the CyanogenMod Nightly through CWM Recovery, the ROM wouldn't install. I noticed the Factory Reset through CWM and that there was an Error mounting the cache partition. I checked the mounts and only the system partition was mounted, I couldn't mount anything else.
So,after essentially bricking the phone, I used Odin and flashed the Stock Firmware back on and followed on as instructed. but the same thing happened again.
Any suggestions would be great. I have been looking at other devices to see if there had been any problems with mounting cache through CWM and to check if they had solutions, but I was coming up pretty thin with explanations. I was thinking if I format through Odin while flashing the firmware back on, that might help?
Thanks in advance, hopefully.
Tried a few more times.
third time clearing cache, the entire screen started to go more and more green.
fourth time made it reboot
fifth time just cant factory reset at all. its ridiculous.
I honestly cant say im doing something different.
Is there a way to break and actually force the cache to be wiped?
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
Argh. I don't understand why I cant access/wipe my cache. is this a recovery problem?
Okay, there may be a problem with the CWM recovery. I have been looking through a few of the threads and comments in particular with Philz touch CWM recovery, and It now works. but there stillseems to be a few problems popping up with installing aosp/aokp roms. backup and restore is working fine. cache/data wipe also working. but it's quite a pain for the whole process to get it to work.
ill post the threads in a bit.
here is the AOKP rom i was referring too

and the recovery thread that helped solves some issues

Unable to mount /system, Error mounting /system!

So guys, I downloaded the latest CM nightly through the CMupdater app, I rebooted into recovery TWRP 2.6.3.0 at that moment I think, when I tried to flash my update it said "Unable to mount /system" and just stood there, I rebooted into recovery again and tried to mount it from the mounts menu without result.
Next I updated to the latest TWRP but the problem persisted, changed to the latest CWM and that too, is unable to mount /system displaying the message "Error mounting /system!"
I seriously don't want to lose my data as this was a simple update so I didn't make a backup but I don't know what the hell else I'm supposed to do.
Oh and BTW, trying to boot to system leaves me at the Google screen for an indefinite amount of time.
Thanks in advance
Edit:Turns out formatting system doesn't delete my data, I got impatient and did that, problem solved.

Can you add SOLVED to the thread title..
Glad to see everything is ok :good:
Thx Josh
So, i just started getting this same error after updating to TWRP 2.8.2.0, I tried wiping the system and still got the error? I downgraded to TWRP 2.8.1.0 and wiped system again, and that seemed to fix the issue. Not sure if it was my own bug or 2.8.2.0 but just wanted to leave feedback for the next person who may be searching for help.

[Q] TWRP backup fails on data partition "E: Unable to stat /data/data/../cache/ .. "

[Q] TWRP backup fails on data partition "E: Unable to stat /data/data/../cache/ .. "
Whenever I try a full nandroid backup in TWRP it always fails once it gets a few hundred files into the data partition. However, it does complete the backup when the data partition isn't selected.
When I first start the backup a bunch of different red error messages come up for various cache files in the data partition.
"E: Unable to stat '/data/data/[variousapp]/cache/[stuff]/[hashvalue?]' "
I've got a rooted T-Mobile Note 3 with Jedi Elite ROM and TWRP 2.8.1.0, however I'm not completely sure that my phone is legitimately rooted. If I try to open the SuperSU app it says "There is no SuperSU binary installed,...", and applications constantly achieve root access then get denied it moments later. Or sometimes the applications achieve root access with no further issues, it's quite random.
Does anyone have any idea what could be going on?
EDIT: It also should be noted that the files in the error messages can be found when using the TWRP file manager, but when using any file manager application with the OS booted the "/data" folder appears empty.
Anyone have any idea?
Thanks
Well.... from the top of my head I would try to do these things:
1) install one of those "check to see if I am rooted" apps and run it.
2) flash a kernel that has been prerooted, i.e.:that it installs the SU binary to the appropriate location.
3) flash one of those .zip packages in twrp that root your phone.
4) check to see if you can make twrp install root for you ( i think when it doesn't detect root binary it offers to do that).
5) reinstall rom only part as a last resort?
Once you restore proper root access you might need to restore proper SELinux labels to /cache /system /data.
Let me know if you get to this part and need specific instructions.
Best of luck

I flashed the latest SuperSU.zip and that ended up fixing root access. The Root Checker app verifies it as well as other applications being granted root access.
I tried flashing CF-Auto-Root in TWRP and it fails.
How do I restore the SELinux labels for those directories?
You caught me on my way to bed but here are the instructions:
From terminal or adb shell
su
ll -Z
(check for any "unlabeled" text for /data /cache /system)
restorecon -Rv /cache
restorecon -Rv /data
mount -o remount,rw /system
restorecon -Rv /system
mount -o remount,ro /system
ll -Z (you should not find any "unlabeled" /cache /data /system)
Let me know how it goes
I tried all those commands from the terminal and it still shows all of the same "Unable to stat" error messages when backing up
The "ll -Z" command, is that supposed to be double pipe or double L? I'd never seen a double L command before so I couldn't get it to work if that's what it is.
Sorry to budge in but I have the same problem too on my oneplus one. Everytime I do something in twrp it saids unable to stat /data/data/com.android.chrome/something I wiped /data and it still does that. I tried to install custom rom and when it starts it saids something is wrong with my system udi and com.android.phone keeps on crashing. So I don't know how I am suppose to fix this. If I format /data I will lose all my pictures,music,apps,etc. since it will wipe /data/media? Any help?
Edit: Upon reading the first post again, I also can't perform nandroid backup because it fails at /data. Which was why I wanted to try different rom and wipe /data to see if it would be fixed.

alright i said screw it and wiped internal storage and it fixed the issue. i had to push ROM onto the new storage through ADB but it seemed to fix the issue.
For anyone who is wondering you need to do a FULL wipe (ie in recovery wipe EVERYTHING including internal storage), then push or mount devices through recovery and put ROM back onto SD card.

Well you fixed it the easy way, I went to the thread on how to turn oneplus one back to stock.
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
I unzipped the 44s Stock ROM and manually flashed each file via adb to it, that cleared up all my problems. I did lose some data, at least at had my apps, messages, and pictures backed up.

I have this same problem with my OPO and I tried a full wipe including internal storage, but the "unable to stat..." problem still persists. Should I try using the "Format Data" option on TWRP instead of just the "Advanced Wipe"? I tried searching online for the difference but I can't really find any information.

So I had my issue on my OPO also, still never confirmed what the actual issue was but after some googling I saw this thread and maybe one more with the same error description.
From TWRP I went Wipe->Advanced Wipe->Clicked ALL boxes.
From what I could tell the issue is actually on the "internal storage" partition which is your emulated SD Card.
I'm not actually sure what the "Format Data" option does tbh I never had to go that far.
Word of warning, make sure you have ADB working and you know how to push files to your phone. You can in theory use the "mount" option from TWRP and connect to a PC as an extendable drive but this functionality is super flaky and is known to not work on occasion.
you don't have to!!!!!!!!!!!
actually i formated it and i was looking for a way to transfer my zip file to internal storage ........... but when i clicked on backup/restore it started to install and booted normally !!!!!!!!!!!!! (by temp boot file)
Sad I am also facing this problem too. At last I have to format everything to get my phone working again, wiping /data does not work, must wipe /data including media.
Internal Storage failure?
This happens to me all the time all of a sudden. I did not change anything at all, except for flashing a new CM version.
I also get a strange stat error, something with google.photo cache.
Yesterday, I have then flashed the new 2.8.6(7) and that gave my phone the rest. It might be because I flashed through TWRP itself into the recovery partition, but now additional to the backup error above when I want to erase dalvik cache, the recovery just hangs. I also can't restore a backup atm.
Now I have reflashed the real 2.8.6.0 recovery and it still hangs when I want to wipe dalvik... wtf is going on here?
And oh yea, my phone does not boot anymore either, it just loops at the flash screen...
UPDATE:
After I found some info on this thread about similar issues, I factory reset my phone with stock recovery (TWRP was not reliable anymore, even the 2.8.6.0 version that was running perfectly before) and then reflashed the latest CM on a wiped internal storage. Now I am up and running again with minimal loss of data due to my TB backups that are scheduled and save to the SD.
But this leaves a very weird feeling back, basically my phone was rendered useless out of nowhere (I was running the previous CM for 2 weeks already), making TWRP backups impossible and forcing me to wipe the internal storage with all media on it without giving me the chance to back it up (MTP in TWPR was also very flaky and died several times half in copy operations). Something is going very wrong with this phone, never ever had that on any of my 5 previous htc devices and the fact that the OnePlusOne users are among the main ones that reported similar issues, I have a feeling it is linked to cheap storage quality. Motorola is a Chinese company now after all... :-/
Hello,
I had the same issue with my Galaxy s4 GT-I9500, it said "E: Unable to stat /data/...", wiping didn't fix, but after I run "format data", it fixed the issue for me.
I have been going through the same issue. I can fix it for 'a while' (by wiping and formatting data) before it comes back again. Anyone knows how to get rid of this once and for all?

Hello guys, my nexus 6p is stuck on twrp. I am running 3.0-2.0 twrp and the latest version of android. I was rebooting the device bc some of apps were misbehaving and clearing the cache. After that, it's been stuck on TWRP. I tried pretty much everything. if its possible, can just copy some of the files and wipe it? Thanks!
Enable MTP in TWRP.
Connect to your PC and transfer your desired ROM
Wipe SYSTEM, CACHE, DATA/DALVIK
Flash the ROM
REBOOT.
@Mavelos said it all, I hope you succeed.
Please keep in mind that if you use a better title you can have much more help

TWRP Error "Structure needs cleaning"

Hey peoples! So long story short, went from xXx's Oreo beta ROM, back to the 2nd leaked Oreo ROM. However, now when I go into TWRP I get "/sbin/postrecoveryboot.sh process ended with ERROR: 1", then after wiping cache/dalvik, I get a "Failed to mount '/system' (Structure needs cleaning)"... What even does that mean? I did a clean wipe coming from xXx's ROM (cache, dalvik, data, system), and am decrypted. I'm also being prompted to confirm I want to reboot, which I haven't had before.. Any help would be greatly appreciated!
I have this problem too. Any solution?
